IMPROVED ELEVATED RAILWAY.

The Schedule referred to in these Letters Patent and making part of thesame.

To all` 'whom it may concern: In the accompanyingdrawings, A A representthe Be it known that 1, RICHARD MONTGOMERY, of the standards supportingmy improved railway. city, county, and State of New York, have inventedThese standards are cmposed of two double-hanged, certain new and usefulImprovements in the Construccorrugated-iron beams a. e, rivetedtogether, face to face,

Similar letters of reference indicate like parts in all (sheet 2 of thedrawings,) to receive the edges of the corrugated beams or plates a, a,so that they shall be tirmly and securely 'united therewith, andretained thereupon without the use of rivets.

Double-corrugated beams F, laid upon the cross-tie beams in suchposition as that the central groove shall be open upwardly, constitutethe rails of the railway. Each beam equals in length the distancebetween the standards, so that the joints between the rails fall uponthe cross-tie beams, as shown in tig. 1.

To make the rails continuous, metallic tie-plates G, tig. 4, areinserted, and secured between the folds of the corrngations at thejoints, as shown in tigs. 4 and 5, to break them.

-The central grooves of the rails may be iilled in, or partially filledin,lalong their whole length, with wooden strips h, continuous with themetallic strips, breaking the joints.

Upon these rails I place triple-flanged wheels K, the tianges thereofbeing so formed as to project pneither side of the rail, and also in thecentral groove, 'the central safety-anges, however, being made much lessprojecting than the other guide-flanges.

The central flange may, it' desired, be omitted, and the wheels usedwith outer iianges alone thereon, and, in such case, the central groovemay be entirely filled. up and closed with an inserted strip.

Having thus fully described my improvements,

I claim therein as new, and desire to secure by Letters Patentl.Standards or supports A, formed by two corru- The nature of myimprovements consists- First, in outwardly curving, in oppositedirections, from a vertical to a horizontal plane, the upper ends of thecorrugated beams, which, united face to face, constitute standards orsupports for elevated structures.

Second, the combination of a corrugated cross-tie beam with theoutwardly-curved ends of the corrugated plates of said improvedstandards, whenused in supporting an elevated railway, to prevent thesame from spreading apart, and at the same time aiford a bearing for therails.

Third, the formation of shoulders on either side of the edge of thecentral longitudinal tie-plate, interposed between the corrugated platesforming the standards for elevated structures, by means of a rib orhead, formed or secured upon' the edges of said tie-plate, so that saidshoulder shall firmly stay and bind the co'rrugated plates, receive alllateral thrust thereof, (thus relieving the rivets from strain, so thata less number is required,) and serve eiiectually to prevent thespread-v ing or opening of the ,folds of the corrugated beams; also, theformation oi grooves inthe shoulders formed by the rib on the edge ofthe tie-plate, to receive and secure the edges of the corrugated plates,and thus obviate the necessity of rivets to unite them; and

Fourth, the combination of a wooden stay-strip with the central groovesof the rails, in continuation of the tallic tie-bars placed therein atthe jointsuof the gated beams, whose upper endsa a are curved inopdually, and secured between two corrugated-metal posite directions,substantially in the manner and for` beams, substantially as herein setforth.- the purpose herein set forth. v 4.
